Inventor: DORF ERNST-ULRICH DR
IPC: C08G75/025
Filed: 1988-10-28
Abstract: A process for the preparation of polyarylene sulphides, preferably polyphenylene sulphide (PPS), having melt viscosities which can be adjusted in a defined manner from alkali metal sulphides and polyhaloaromatic compounds in a polar solvent in the presence of a ketone or pinacone. The resultant polyarylene sulphides having defined melt viscosities are distinguished by high melt stability and a low chlorine content. They cause little corrosion on the reaction vessels used for their preparation.

Abstract: The rate gyro can be used on missiles capable of being subjected to very high acceleration. It consists of a more or less plane plate (12) with 4-fold symmetry about an axis roughly perpendicular to its plane. The plate is formed, at least partly, from a piezoelectric material. Its two large faces carry both the electrodes (E) for exciting the plate at resonance, these electrodes being distributed uniformly around the axis, and the electrodes (D) for detecting the vibrations of the plate, these electrodes being located in the same plane and arranged so as to detect the stresses caused by the forcing field and by the Coriolis forces during the rotation of the plate about its axis. The plate is preferably square. The power supply to the excitation electrodes (E) is such that they excite vibrations of the plate symmetrically about one of the directions (X) but antisymmetrically about the perpendicular direction (Y), so that the forcing vibrational mode and the Coriolis mode are 90 DEG  apart. <IMAGE>

Abstract: Procédé consistant à remplir un support en un matériau actif avec une pâte préparée en malaxant un oxyde de plomb présentant une teneur en minium allant jusqu'à 90 % ou un mélange de cette poudre d'oxyde de plomb et d'une poudre de plomb avec de l'eau et de l'acide sulfurique en tant que composants principaux. Etant donné qu'on utilise une poudre d'oxyde de plomb présentant une teneur en minium allant jusqu'à 90 %, le minium à la surface de l'oxyde et l'oxyde de plomb dans le noyau des particules sont liés directement et la force de liaison entre les matériaux actifs lors du malaxage de la pâte est améliorée. La plaque ainsi préparée assure une meilleure adhésion de la pâte sur le support de matériau et une force de liaison importante entre les matériaux actifs. Par conséquent, le rendement du chargement de formation peut être amélioré grâce au minium et la durée de vie des accumulateurs s'en trouve prolongée.
